I have a Intel CD 1.66 GHz Mac Mini and I'm trying to figure out my upgrade choices. Which Core 2 Duo CPUs work with my Mini? The partial list I've compiled include: T7200 (2.0GHz) T7400 (2.16GHz) and T7600 (2.33GHz). Of course, I might be mistaken that the above work, and I'm sure there are other CPUs not on the list. Please let me know. Thanks!
